Description
Technical field
The present invention relates to the electric bicycle field, particularly a kind of rim of electric bicycle is used duraluminum.
Background technology
Electric bicycle is because speed is fast than ordinary bicycle, uses more flexibly than automobile, and it is wider to adapt to road, therefore, has become a kind of important vehicles of people's trip.At present, the electronic owning amount voluntarily of China is very big, and people also improve each item performance of electric bicycle, and wherein important improvement relates to further and cutting down the consumption of energy, and improves the actual service life of single charge.The more improvement that relates to rechargeable battery in these researchs.
And another important aspect, can be from the material of car body, alleviating car body weight also can save energy, thereby improves the actual service life of single charge.The agent structure of conventional electric bike is seldom used aluminum alloy materials, but along with the continuous evolution of technical progress and complete processing is ripe, duraluminum is used by more producer as a kind of equivalent material gradually.With regard to wheel rim, prior art has that to select 7XXX for use be the report of alloy.
Yet, because the 7XXX material is because solidus curve is lower, so the extruding quenching temperature is low; For follow-up processing; The control temperature out will be lower than quenching temperature in extrusion process, otherwise can be owing to the high alloy content of 7XXX alloy, and material seasoning is rapidly strengthened; Must generally in 1-2 days, accomplish aluminium wheel rim bending, punching pcketing processing in the extremely short time.In case surpass this timing node, just must carry out to continue processing after the solution heat treatment.If not carrying out solution heat treatment processes, in the punching pcketing course of processing,,, also can cause the surface to produce orange peel phenomenon owing to the reduction of plasticity even cracking do not occur because plasticity can produce cracking phenomena inadequately, have a strong impact on attractive in appearance.The cost rising will inevitably appear in solid solution, production efficiency is low if carry out again, and the disappearance owing to extrusion effect after the solid solution simultaneously can cause degradation.
If the extruding temperature out is lower than the quenching point temperature, make material fully not quench, just mean and will reduce the extruded bars temperature that cause squeeze pressure to increase severely, extrusion speed sharply descends, efficient reduces, and damages container and extrusion mould simultaneously easily.And, make it in its follow-up course of processing, must carry out solid solution competence exertion alloy property owing in extrusion process, do not obtain best quenching temperature.
In sum, by existing aluminum alloy materials, no matter adopt which kind of technology, it is low all inevitably to face production efficiency, can not give full play to material property simultaneously.
Summary of the invention
To the deficiency of prior art, one of the object of the invention is to provide a kind of rim of electric bicycle to use duraluminum.The wheel rim intensity that adopts this duraluminum to prepare is high, unit elongation is good, welding property is good.
To achieve these goals, the technical scheme of the present invention's employing is following:
A kind of rim of electric bicycle is used duraluminum, and said duraluminum is made up of following component by weight percentage: Si 1.5～2.5; Cu 1.5～2.5; Mg 2.0～3.2; Zn 0.4～0.8; Ti 0.2～0.6; Zr 0.35～0.50; Surplus is aluminium and unavoidable impurities.
Preferably, said duraluminum is made up of following component by weight percentage: Si 1.8～2.2; Cu 1.8～2.2; Mg 2.4～2.8; Zn 0.5～0.7; Ti 0.3～0.5; Zr 0.4～0.45; Surplus is aluminium and unavoidable impurities.
Most preferably, said duraluminum is made up of following component by weight percentage: Si 2.0; Cu 2.0; Mg2.6; Zn 0.6; Ti 0.4; Zr 0.43; Surplus is aluminium and unavoidable impurities.
Beneficial effect of the present invention is:
The present invention is directed to the characteristics precise design of electric bicycle and the composition of control duraluminum, each alloy element synergy of duraluminum makes it have very high intensity, good unit elongation, low seasoning effect, good welding performance.Of the present invention aluminium alloy extruded after, tensile strength >=430MPa, surrender >=380MPa, unit elongation >=8%; And machine-shaping property is good, satisfies the use needs of electric bicycle fully.
